SPECIFICATION forming part of Letters Patent No. 734,895, dated July 28, 1903.

A lieation filed December 26, 1902. Serial No. 136.662. (No model.)

Be'it known that I, J ULES LAFAURIE, a citt zen of the Republic of France, residing at Oastelmoron-on-the-Lot, in the department; of Lot-et-Garonne, France, have invented certain new and useful Improvementsin Stenographic Printing or Writing Machines, of which the following is a specification.

This invention relates to machines for pri nting stenographic signs representing the various sounds ofthe human voice side by side upon a strip of paper by making on said strip the impression of one or of several types carried by a system of ten key-levers having their heads or keys arranged to correspond with the positions of the ten fingers and thumbs of both hands of the operator. Such machines havebeen heretofore made; and the object of this invention is to improve them by simplifying their construction with a view to facilitating their operation, rendering them capable, of greater speed with less exertion and less noise than heretofore, and causing them to make plainer and clearer impressions.

j sists in providing such machines with means With this object in view the invention conwhereby the paper willbe fed forward during each stroke of one or more of the keys, but will be held substantially at rest at the'time of making the impressionswithout requiring any spring, stops, or the like usual accessories.

i The invention further consists in the improved construction, arrangement, and combination of the partsof such a machine, which will be hereinafter fully described and afterward specifically claimed.

I have illustrated a machine of this class a constructed in accordance with my invention in the accompanying drawings, in whichvation; and Fig. 2,'a top plan view of the same with the paper-rolls, paper, and paper-feeding mechanism omitted, parts of such omitted devices being indicated in outline in dotted lines. l Like reference characters indicate thesame parts in both figures. Referring specifically to the'drawings, 1 indicates the rigid frame of the machine, in which is mounted on suitable bearings a shaft carrying the rolled strip 2 of paper to lever, and key 2".

intermediate their ends, as at m, and above Figure 1 is a view of the same in side ele-' [be printed upon by the type representing the various stenographic characters, said type being mounted upon the inner ends of a set of ten key-levers Z, which diverge outward and have their outer ends, which carry keys m, in the best positions to be pressed by the fingers and thumbs of both hands of the operator, these keys and levers being arranged in a left-hand and a right-hand series of five each, between which is mounted a spacing The levers Z are pivoted them and inside of their pivotal points is ;mounted a transverse bar 3 in such position ithat pressure upon any one or more of the keys will cause that portion under the bar to raise and raise the bar with it. The bar 3 is mounted upon the inner ends of arms 72, projecting from a rock-bar p, pivoted at l in. the frame of themachine and in a bracket q. Se-

cured on top of the cross-bar is pivoted the lower end of a link 5 adjustable in length by being madein two right and left handthreaded sections joined by a coupling 70.

A short lever 6 is pivoted to the frame of the machine and carries at its free end a. pawl 7, pivotally secured thereto at 8 and engaging at its end the teeth of a ratchet-wheel 9, secured upon a shaft 10, journaled in hearings in the frame of the machine and carrying aroller 11, upon which the strip 2 of paper is wound after having the characters impressed upon it. The upper end of the link 5 is pivoted at 14 to the lower lever 6 intermediate its ends, so that when a key is depressed its lever raises cross-bar 3 and carries up the link 5, which has been previously adjusted so that when the type strikes the strip of paper stretched under a platen or bearing 13 the lever 6 will be raised to or slightly beyond a position in line with the i ceased to move the ratchet-wheel and the roller when in line with the lever 6 and will be drawn slightly backward when moved beyond that line, and consequently the strip of paper will gradually be brought to a stop at or slightly before the moment the type strike it, thus insuring a clear unblurred imprestype ends of the key-levers is pivotally mounted a rock bar or lever 12, in the free end of which is journaled an inking-roller 23, which when the type and key-levers are in their normal positions of rest lies normally upon the faces of the type, as clearly shown in Fig. 1, being held in said normal position by a spring 24, and slides backward oh? the type when the type are raised to make" an impression, being held against the ends of the key-levers by said spring 24, as shown in dotted lines in Fig. 1, at the time the type strike the paper. When the type drop back from the paper after the impression is made, (owing to the release of the. keys from the hand-pressure,) the roller 23 again drops forward to its normal position, resting on the face of the type. sion of one or of any number of the type may be rapidly and easily made on the paper, the type being automatically inked each time and the paper being stationary at the moment of impression, and to render the operation of the machine practically noiseless all contacting parts may be suitably cushioned with leather, felt, or the like, after the manner of cushioning the parts of a piano-action.

Having thus fully described my invention, what I'claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a machine of the character described, the combination with a roller upon which a strip of paper may be wound, of suitable typebearing key-levers, and means, actuated directly by the action of the key-levers in making an impression, for rotating the paperroller with gradually-decreasing speed and In this manner the impres-.

stopping it at or slightly before the moment of impression, substantially as described.

2. In a machine of the character described, the combination with the paper-feeding roller and its ratchet-wheel, of a lever pivoted to the frame of the machine, a pawl pivoted to the free end of the lever and forming with said lever a pair of toggle-levers, pivoted type-bearing key-levers, a cross-bar above said levers, and a link pivotally connected at one end to the cross-bar and at the other end to the pawl-lever, said toggle-levers being mounted in position to bring them into or slightly beyond a straight line with each other atthe end of the impressing movement of the key-levers.

3. In a machine of the characterdescribed, the combination with the paper-feed roller, of a lever pivoted to the frame of the machine, a pawl pivoted to the free end of the lever,

key-levers, and connections between the keylevers, and the pawl-lever located between the pawl and the pivot .of the lever to cause the pawl and pawl-lever to act as toggle-levers and to bring them into or slightly beyond a line with each other at'the end of the stroke of the key-levers, substantially as described.

4. In a machine of the character described, the combination with paper rollers and a platen over which the paper is stretched, of key-levers bearing type on their upper sides and having smooth ends and actuated to strike the type against the paper on the platen, a rock bar or lever pivoted to the frame of the machine, an inking-roller carried by said rockbar and yieldingly held on the face of the type when at rest and sliding oif the type and held against the ends of the key-levers at the moment of impression, substantially as described.

In testimony whereof I affix my signature.
